` 2 Claims. 3f-,This invention relates to tabulating machines employingrecord cards and deals particularly ,i with a multiplying machine of thetype shown in latent Number 2,165,230, granted July ll, 1939,

to J. M. Cunningham.

lThe invention to be hereinafter described is an addition to machines ofthe above character, which in practice will eliminate one or moreoperations required under the ordinary use. The present record cardcontrolled machines used for multiplying are so constructed that in thefield in the card where recordings are to be made the machine willrecord zeros until the first signicant figure appears. It will beunderstood by those skilled in this art that the multiplying machinereferred to will record a result in a predetermined iield, which fieldcan be used to f control a check Writing machine and that when the cardis later used to control a check writing machine the Zero recordingsahead of the signicant figures in this eld will be ignored by the checkwriting machine. To print the customary asterisks or stars ahead of thesignificant figures on the check, the usual practice is to sort thelresponding to the number of zeros ahead of the iirst signifcant iigure,said recordings being positioned to operate magnets on the check writingmachine that cause the machine to print asterisks or equivalent signs.

Under my invention a change over device is incorporated in themultiplying machine that will change over the connection from the readout to the zero magnet, so that the zero magnet will not respond to theread out but an auxiliary magnet in the multiplying machine will beenergized instead. The auxiliary magnet referred to is one of the extramagnets incorporated in a multiplying machine as standard equipment andis arranged to cause recordings above the regular ileld in the card.Normally it is not used in the regular machine operation. After thechange over has been made the auxiliary magnet will be operated by thezero connection to the read out untila positive number is reached in theread out, whereupon the change over will switch the connection back tothe zero magnet and zeros will be properly recorded for the remainder ofthe iield in the card. The result is a series of signs on a check. Thedevice may be installed upon a standard multiplying machine and operatedwithout affecting any other parts or operations of the machine exceptthose specically mentioned. The recordings mentioned herein are theconventional holes punched in record cards by a plurality of punchmagnets under control of the read-out lines.

In the drawing I have shown a simplified illustration of how myinvention may be applied to a conventional multiplying machine of thetype shown in the above mentioned patent. Figure, l is a wiring diagramshowing the selector magnets with my change over device incorporatedtherein; Figui-e2 shows a fragmentary part of the multiplying machine inconjunction with an auxiliary circuit for operating the change overdevice shown in Figure l; and Figure 3 shows a conventional payrollcard.

Briefly stated, my invention consists of an automatic change over devicebetween the zero magnet and an auxiliary magnet whereby the read outcircuit normally connected to the zero magnet may be switched over tooperate the auxiliary magnet. In the drawing I have shown a series ofselector magnets designated to 9 inclusive, and l i and i2. Thesemagnets correspond to the magnets designated 23 in Patent Number2,126,595 granted August 9, 1938, to H. Weinlich et al. In Figure 2, Ihave generally designated these same magnets 126. With respect to themagnets, it is to be understood that the ordinary multiplying machinecarries twelve magnets, ten oi which are used to punch holescorresponding to numerals, and two of which, namely i l and i2, areusually not employed in the ordinary multiplying operation. In myinvention I utilize one of the magnets, either l l or i2, in thisinstance magnet l2, for my purpose, and whenever the magnet i2 ismentioned herein it is to be understood that this term is intended toinclude any magnet that causes a recording in the card above the regularfield. Referring again to Figure l, it will be noted that one side ofthe magnets, 0 to 9, inclusive, are connected to conductors Il to 9respectively, which lead to their respective connections on the read outdevice and correspond to wires 52 (Fig. lb of the Cunningham patentmentioned above). Since this invention is concerned solely with anaddition which aects only two of the magnets, and since the operation ofthe invention is not dependent 'upon nor is connected with any otherelectrical operation of the machine, the description will not includeoperations of other parts of the machine but will be confined to thatpart only which is aiected. The read out device mentioned hereincorresponds to the conventional circuits illustrated in Fig. 1b of thesame Cunningham patent. It will be noted, with respect to Figure 1, thatthe lower side of the magnets I to l, inclusive, are connected to a lineIl and that the lower side of the magnets Il and I2 are connected to aline Il. Both lines I3 and Il are connected to line 5l, whichcorresponds to line 54 of Cunningham. In the line I3, I incorporate arelay coil B.

Referring to Figure 2, it will be observed that I have shownfragmentarily a machine embodying the aforementioned selector magnetsI20 and a card carrier rack 'Il which corresponds to the card carrierrack 14, shown in Fig. 16, of the Weinlich patent. In conjunction withthe card carrier rack, I incorporate a ycircuit comprising switch S, keyK, relay coil A, contact points IA, contact points IB, and key L. Thecircuit is connected to the same source of supply through line 54 andline 55. It will be noted that key K is paralleled across the contactsIA, the purpose of which will become apparent presently. It will,

also be observed that the coll B is Aparalleled by contacts 3A and thatdouble contacts 2A are arranged in the line II' connecting the II magnetto the read out device so that the control time the contact points 3Awill close and shunt out the coil B and the magnets II to 9 inclusivewill then operate in the conventional way. Ar the rack continues totravel, it will encountex and open the switch L, thus breaking theauxiliary circuit independently of the key K and the contacts IA. It isto be understood that the switch L is a precautionary switch and isplaced in the circuit merely to insure that the circuit will be openedat the end of the card travel in case no significant figures appear inthe check writing field. The result, as shown-on the card C, is a seriesof recordings I6 in the upper portion of the card above the regularcontrol eld, said recordings being arranged to control punch magnets ina check writing machine which, as before stated,'have been adapted toprint the desired signs such as asterisks or stars.

The above described operation whereby zero recordings in the checkwriting ileld are converted into other recordings outside the regularileld to control magnets in a check writing maof the read out device maybe switched from the 0 magnet to theV I2 magnet and vice versa. On thecard carrier rack 14, I mount a fixture M, which in this instance isshown as a form of an extending arm that is adapted to engage and closethe key K as the rack travels a predetermined distance, whichdistancefis determined by the fleld on the card that controls the checkwriting machine. The key L is also arranged to be engaged and openedafter the rack travels a predetermined distance beyond the closing ofthe key K.

In operatin, a record card having items punchedin different columns,such as is illustrated in Figure 3, is fed into the multiplying machineby means of the rack 14, and the machine calculates the various itemsand as the card travels records a result in the check writing fielddesignated I5. In recording the result in the check writing field, themultiplying machine under the ordinary set-up will record zeros untilthe first significant figure is reached, whereupon it records the actualamount carried over into the field. According to my invention, as thecard carrier. rack 'I4 carries the card C into the machine, the arm Mwill engage and close the key K as the check writing eld I5 enters therecording position in the machine. Assuming that the switch S is closed,the coil A will become energized and will close the contact points IA,thus forming a circuit independent \of the key K, which by virtuelof thetravel of the carrier rack 'Il is only momentarily closed. At the sametime coil A operates contacts 2A, which disconnects the Il magnet, andplaces the I2 magnet under control of the read out; Also, contacts 3Aare opened, thus throwing coil B in` series with line I3. According tothis circuit, any impulse from the read out `normally transmitted to the0 magnet will be transmitted to the I2 magnet instead. As`explainedhereinbefore, the I2 magnet is arranged to cause recordings in the cardabove the regular field, which recordings are subsequently used tooperate magnets in a check writing machine that prints asterisks orequivalent signs on a check. This arrangement will hold until any one ofthe other magnets from I to 9 are energized, which will in turn energizethe coil B and break the contacts IB, thus deenergizing the coil A andallowing the contacts 2A to swing back and connect' the zero magnet toits proper read out connection. At the same chine for the purposedescribed is automatically performed in the multiplying machine, thuseliminating sorting and rerecording of the cards before use in the checkwriting machine.

The means employed for the purpose is simple, inexpensive, and may beincorporated in a conventional multiplying machine with minoralterations.
